Today, we are excited to bring a new twist to annotations: the ability to collaborate on them with other YouTube users. Now you can invite anyone you like to create speech bubbles, notes and spotlights on your videos.

Enabling Collaborative Annotations is easy. First, go to your annotations editor (which you can find in My Videos or by going directly to your video's watch page) and retrieve the special annotations link. Then send it out to your friends. Once they click on the link, they will be allowed to add annotations to your video. If you don't like what they write you can always delete their annotations, and you can also disable access to the annotations URL so that no more can be added. Naturally, you can edit or delete anything you write on someone else's video.

P.S. Even though we think annotations are really cool and give you yet another reason to start interacting even more deeply with videos on the site, we realize some of you are "old school" and prefer to see just the video and nothing more. For this reason we've added a setting that lets you permanently disable annotations. Check out this Help Center article for more information.
